The present invention will be described in further detail with reference to the accompanying drawings.

An embodiment according to the present invention is shown in conjunction with fig. 1 to 5, in which it can be seen that:

the utility model discloses a projection curtain, its theory of operation is:

first, the projection curtain includes a bottom fixing groove 101, a rotation fixing bracket 102, a connecting rod 103, and a bending plate 104. This mechanism is tight mainly through the rotation of two bottom fixed bolsters 101 for connecting rod 103 to be pressed from both sides and makes crooked panel 502 drive the curtain 503 crooked to give other people better watching experience. The bottom fixing bracket 101 is usually placed on the ground to support the base, and the bottom fixing bracket 101 can perform the requirement of a relatively flexible rotation completion mechanism. The bottom fixing bracket 101 rotates along the longitudinal connecting shaft 402 to change the position, and drives the relative position of the upper rotating fixing bracket 102 to change, so that the distance between the two opposite plate clamping brackets 501 is reduced, the bent plate 502 is further bent, and therefore the curtain 503 connected with the bent plate 502 can be bent synchronously to meet the use requirement of the mechanism.

The bottom fixing bracket 101 includes a fixing slide rail 201, a coupling hole 202, a receiving groove 203, and a fixing bracket hole 204. The fixed slide rail 201 can meet the requirement that the rotating fixed support 102 horizontally slides on the fixed slide rail to change the front and back positions of the curtain, and meanwhile, the fixed slide rail 102 is further provided with three fixed support holes 204, so that the rotating fixed support 102 is fixed in the vertical direction, and the stability of the structure is ensured. Wherein the fixed slide rail 201 is connected with the rotary fixed bracket 102 in a sliding way through a rotary connecting shaft 301, and the fixed bracket 101 is connected with the connecting rod 103 in a rotating way through a longitudinal connecting shaft at the connecting hole 202. When the curtain 503 is not used, the rotating fixing support 102 can be rotated to the horizontal position and placed in the accommodating groove 203, so that the occupied volume can be effectively reduced, the use and the accommodation are convenient to switch, and the curtain is convenient to work and use at home.

The rotation fixing bracket 102 includes a transverse rotation connecting shaft 301, a transverse locking nut 302, a transverse washer 303, and a curtain fixing groove 304. Wherein the rotary fixing bracket 102 is locked with a transverse gasket (303) through a transverse locking nut 302 to form a fixed connection with the bottom fixing bracket 101. The rotating fixing bracket 102 is normally placed in the accommodating groove 203, when the curtain 503 projection is needed, the rotating fixing bracket 102 needs to be rotated to a vertical position, and the rotating fixing bracket 102 slides into different groove holes of the fixing slide rail 201 according to different required angular distances and is fixed through a transverse locking nut 302 and a transverse gasket 303. After the curtain 503 uses, can take off curtain 503 one side is fixed to roll up curtain 503 and arrange in opposite side curtain fixed slot 304, prevent when reducing the volume of accomodating that the curtain 503 deposition is clean and influence the condition appearance that watches experience not convenient for.

The connecting rod 103 mainly satisfies the connection and relative rotation relationship between the two bottom fixing brackets 101, and limits the distance between the two rotating fixing brackets 102, and needs to be matched with the length of the curtain 503 to a certain extent, so as to facilitate the formation of the curved surface of the curtain 503. The connecting rod 103 mainly comprises a longitudinal locking nut 401, a longitudinal rotation connecting shaft 402, a longitudinal gasket 403 and a connecting rod body 404, wherein the connecting rod body 404 is locked with the longitudinal gasket 403 through the longitudinal locking nut 401 to form a fixed connection with the bottom fixing bracket 101. The bent plate 502 is also affected by the length of the connecting rod, and the bent plate 502 is mainly made of a material with better toughness and is convenient to bend. The curved plate 502 is tightly attached to the curtain 503, so that the deformation can be well formed on the curtain 503 to achieve the curved surface effect. Wherein the plate clamping bracket 501 is fixedly connected with the curtain fixing groove 304, and the plate clamping bracket 501 is fixedly connected with the bent plate 502.

Recently, due to the continuous emergence of mobile phones, computers, televisions and the like with curved screens, more and more people know the advantages of the curved screens relative to the traditional screens, and therefore the products with the curved screen structures are more prone to being purchased. Therefore, the projection screen can be produced. Firstly, the curved screen can better improve the sensory experience. Because the eyeball of the person is convex and has radian, the radian of the curved screen can ensure that the distance of the eyes is equal, so that the curved screen can bring better sensory experience. And from the practicality angle, bigger display screen adopts curved surface screen structure can be more economized space, easily operation. This projection curtain can only be arranged in on the fixed wall for general projection curtain, can carry out the removal in the space, and the flexibility is higher. And this curved surface projection curtain fixed establishment all has very high degree of freedom in curved surface radian setting and fore-and-aft distance, can satisfy user's different demands. The storage aspect occupies a small use volume as much as possible, so that the product is excellent in comprehensive practicability and meets the use requirements of people at the current stage.

The technical scope of the present application is not limited to the contents in the above description, and those skilled in the art can make various changes and modifications to the above embodiments without departing from the technical spirit of the present application, and these changes and modifications should fall within the protective scope of the present application.
